Abstract
A device for controlling the respiration to a patient from a respirator in accordance with the partial pressure of the carbon dioxide in the arterial blood or tissue measured in the alveolar expiration air comprises a connection from the patient and the respirator which includes a housing portion with a dead space cavity through which the respiration air must pass. The housing has a partition wall which bounds a part of it and it is connected to a drive motor for moving the partition wall outwardly and inwardly in order to enlarge or reduce the size of the cavity. This outward and inward movement is controlled by a control which is actuated by a sensor which senses the partial CO.sub.2 pressure in the respiration gas and regulates the partition wall so as to vary the partial pressure of the CO.sub.2 without changing the chosen minute volume of respiration and the pressure.
